MVC Web API Post不会从HttpClient调用

Question

我有以下模型

public class Customer
{
    public string Name
    {
        get;set;
    }

    public string Address
    {
        get;
        set;
    }
}

以下WebAPI方法

    [Route("PostCustomer")]
    [HttpPost]
    public Customer PostCustomer([FromBody]Customer c)
    {
        return c;
    }

以下客户端代码

Customer cust = new Customer() { Name = "abcd", Address = "test" };
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost:11581");
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var response = await client.PostAsJsonAsync<Customer>("api/values/PostCustomer", cust);

WebAPI方法永远不会被调用，我从Web API获得的响应没有内容。当我尝试相同的获取它工作正常。
